  • step S1008 the near field communication server of the network which the user is currently in returns the local network list.
  • step S1010 the home near field communication server obtains the PLMN lists permitting condition authorization according to the subscription information, and obtains the PLMN list of the local network from S1004; the home near field communication server selects the PLMNs that are overlapped and combines them into the PLMN list needed to be further authorized.
  • step S1012 according to the PLMN list needed to be further authorized obtained in step S1005, and according to the PLMN ID in the list, the FQDN of the corresponding near field communication server is deduced, the IP address of the near field communication server of the PLMN is obtained by inquiring the DNS, and then the authorization request carrying the user identity is initiated to the address.
  • step S1014 the near field communication server decides, according to the local configuration, whether the user is authorized to conduct the D2D service, and returns the authorization result back to the home subscriber near field communication server.

  • FIG. 11 shows a flowchart 3 of an authorization processing method according to an example of the present invention in a scenario where a user is in the roaming state and the PDN GW is in the visited network. As shown in FIG. 11 , the flow includes the following steps.
  • step S1102 after a terminal accesses the visited network and establishes a connection with the PDN GW of the visited network, the PDN GW notifies the UE that it is currently in the visited network.
  • the terminal sends an authorization request to the visited near field communication server.
  • the terminal inquires the corresponding IP address through the DNS according to the FQDN of the visited near field communication server, and then communicates with the address.
  • the terminal deduces the FQDN of the visited near field communication server according to the PLMN ID of the visited network.
  • the PDN GW can also return, in the process of establishing the connection response, the IP address of the home near field communication server back to the terminal according to the user's request.
  • the authorization request message contains the information about the PLMN which the user is currently in and the user identity, for example the IMSI or the MSISDN.
  • step S1104 If the visited near field communication server judges that the user is in the roaming state according to the user identity, the visited near field communication server deduces the FQDN of the home subscriber near field communication server according to the user identity, inquires the DNS to obtain the IP address of the home near field communication server, and sends an authorization request to the address, herein the message carries the information about the PLMN which the user is currently in and the user identity.
  • step S1106 if there is no subscription information of user in the home near field communication server, the home near field communication server requests the home subscriber server for the subscription information of user; the home near field communication server stores the subscription information in the local database after obtaining it. The home near field communication server obtains the PLMN list permitting full authorization and the PLMN list permitting condition authorization according to the subscription information.
  • step S1108 according to the PLMN list permitting condition authorization obtained in step S1103, and according to the PLMN ID in the list, the FQDN of the corresponding near field communication server is deduced, the IP address of the near field communication server of the PLMN is obtained by inquiring the DNS, and then the authorization request carrying the user identity is initiated to the address.
  • step S1110 the near field communication server decides, according to the local configuration, whether the user is authorized to conduct the D2D service, and returns the authorization result back to the home subscriber near field communication server.
  • step S1106 If there are multiple PLMNs in the PLMN list permitting condition authorization which is obtained in step S1106, step S1108 and step S1110 are repeated.
  • step S1112 after receiving responses from the near field communication servers of all the PLMNs needed to be further authorized, the home subscriber near field communication server combines the PLMN list permitting the D2D service in the responses and the PLMN list permitting full authorization which obtained in step S1106 into the authorized PLMN list and returns the authorized PLMN list back to the visited near field communication server.
  • step S1114 the visited near field communication server deletes the PLMN which is not in the local network list from the received authorized PLMN list according to the local network list configured locally.
  • step S1116 the visited near field communication server forwards the authorized PLMN list after the processing of step S1114 to the terminal.
  • the terminal After receiving the PLMN lists, the terminal can decide whether to initiate the D2D service according to the authorization result.
  • the UE has no need to directly communicate with the local/visited near field communication server, so the technical problem 2 in the related art is avoided; the home near field communication server obtains the local network list from the near field communication server of the network which the user is in, so the technical problem 1 in the related art is avoided.
  • a piece of software is further provided, which is used for performing the technical solutions described in the above examples and alternative examples.
  • a storage medium in which the above software is stored; the storage medium includes, but is not limited to: a compact disk, a floppy disk, a hard disk and an erasable memory.
  • modules and steps of the present invention can be implemented by a general-purpose computing device, and they can be centralized in a single computing device or distributed on a network composed of multiple computing devices; optionally, they can be implemented by a program code which is capable of being executed by the computing device, so that they can be stored in a storage device and executed by the computing device; and in some situations, the presented or described steps can be executed in an order different from that described here; or they are made into integrated circuit modules, respectively; or multiple modules and steps of them are made into a single integrated circuit module to realize.
